Malnutrition is one of the major health problem in pre-school children cause of mortality and morbidity in Bangladesh. The aim of the study was to determine the associated factors of double burden of malnutrition among pre-school children in Rajshahi City, Bangladesh. By using standard procedure, 250 pre-school children were randomly selected for measuring nutritional status, during March 2017 to September 2017. Data was collected by using a semi-structured questionnaire, consisted of socio-economic, dietary and feeding pattern related information. Measurements of weight and height were obtained with digital machine according to standard procedure. Multistage random sampling, chi-square test and multinomial logistic regression were used in this study. Body mass index for age was used for determining malnutrition. The prevalence of malnutrition was 44.8% among children in this study. Normal weight was considered as reference category in multinomial logistic regression analysis, which demonstrated that the predictors of child malnutrition was parent’s education, income, source of drinking water, hygienic latrine and environment, initial breastfeeding, living conditions and mother’s occupation. Multinomial logistic regression analysis showed that a mother, who was uneducated (OR= 6.19 CI: 2.110-18.159; p<0.01), primary educated (OR= 4.33 CI: 2.089-8.989; p<0.01) and secondary incomplete (OR= 3.46 CI: 1.416-8.486; p<0.01) had more chance to get underweight children than their counterparts. Likewise, children who were living in soil made (OR= 6.30; CI: 0.168-1.365; p<0.01) and tin shade houses (OR= 2.05; CI: 0.960-4.388; p<0.05) had more chance to get underweight than who lived in building.
